As a major CO2 emissions contributor (2% globally), the aviation industry is desperate to find alternative ways to create kerosene, jet fuel, without utilising fossil fuels. Sustainable aviation fuel (SAF) is essentially jet fuel that uses any non-petroleum-based renewable source for its feedstock; biomass, human/animal waste, agricultural by-products, all are SAF examples that can represent anywhere up to 80-90% lower carbon emissions rates compared to conventional jet fuel.
Post COP28, heavy emitters like aviation are eager to push harder for fundamental changes that will lead to a lighter carbon footprint. Given that the estimated global consumption of jet fuel by commercial companies was 86 billion gallons in 2023, the need to secure and upscale SAF production is greater than ever before. Innovations that lead to more reliable, cheaper and easier production methods may quickly become industry-changing events this year.
